compute_total_readout_time
- bidsaid.metadata.compute_total_readout_time(effective_echo_spacing=None, recon_matrix_pe=None, use_fallback_trt=False)[source]
Compute the total readout time.
The following formula is used:
total_readout_time = effective_echo_spacing * (recon_matrix_pe - 1)
where: echo_train_length = epi_factor + 1 (Number of echos acquired every radiofrequency pulse (repetition time))
Parameters
- effective_echo_spacing
float The effective echo spacing in seconds.
- recon_matrix_pe
int The number of pixels in the phase encoding axis of the reconstruction matrix.
- use_fallback_trt
bool If True, a fallback readout time of 0.03125 is used.
Returns
- float
The total readout time in seconds.
